Abstract

As a new generation of solid-state lighting source， white LED has shown outstanding performance advantages in energy conversion efficiency， brightness， chemical stability and environmental protection， and is widely used in the lighting field. Among its various white light construction methods， “near ultraviolet LED+ multicolor phosphors” is more conducive to the realization of high color rendering index and low color temperature healthy lighting， which has been highly concerned. The development and performance control of high-quality multi-color luminous materials is also a research hotspot in recent years. This paper introduces the latest development of Eu

/Ce

activated luminescent materials for near ultraviolet LED， including the performance optimization of commercial powder and the development of new system， and discusses the means of material design and performance control. Finally， some opportunities and challenges of luminescent materials for near ultraviolet LED are discussed， This review provides reference and guidance for the development of white LED.
